- .The baselis proyided ,with ,a suitabley bolt or stud, d, `lrwhich isrigidly fixed'l to it and proieets 'frsmf tbs .fase .then-set nen whichs'f-piv:oisllymounted slarrirerrets lhel'ds'lm rgsaid holder, its outer`end provided with an aperture Safes? serine itbs headsildgeffefmatchfbz- "life @Sirsdsgsld mbsfin position `in the aforesaidopening, the outer end of ,the helder may hes'plit to form more or lessvelastic or spring jaws which close upon the head of the match.

The holder has' a. thickened 'hub portion through which the bolt, cl,projects, and the bore of said vhub portion is enlarged and lmade at anangle to the' axis of the bolt or stud, as shown in FiggQ, whereby theholder may, in addition to its axial movement about the stud, have ayrocking movement in ythe direction of the length of the stud'and transverde to the face :of the base, to facilitate the insertion of |`thematch and the movementof the match head past ythe igniting surfacehereinafter described, Whensetting the holder in its operative4position, The pivotedholder is also provided with a heel portion, 4b3,adapted to engage loehindl a suitable trigger, e, Vwhich isy slidablymounted in bearings e, formed on or struckout from' the base plate, saidtrigger .being en'- circled by a coil spring, f, which alloivs thetrigger to he depressed to release thehlder, and which is adapted toexpand and form an abutment fortheheelend ofthe holder whereby `saidholder is held yagainst moves mentluntilrreleased bythe trigger, saidtrigger haying, also, a finger piece,lg, by`vvhieh it may he depressedagainstxthe tension'of its `spring to krelease sthe holder, as Will "hewell understood in thisart.

Surrounding ,the bolt ,or stud, d, isy a spring, c, one `endof which isfixed to `the stud 1and the other-end isliitted to an opening, lorformed r`in the holder, said spring adaptedstohe placed under tensionwhen the holder isreset or moyed into its operative posit-iemandoperating tofpfroject or carry the attached match over `a corrugated "orroughened surface, 47L, suitably secured to the fees Of' 911s besse, t0thereby ,ienfldis match, when the Vtriggerfe, Vis v\vi thdravvn from itsWengage'ment YWit11',the r1heel endof the'holder.` W

i1in the bass plate .is alsoffprmed airone` leased i111 thslmeeessybefrs, dsssbegl; .and

.. the base.

roughened surface, h. To insure the proper register of the match headwith .the aforesaid opening, le, I construct the base plate, a, with ashelf, stop or lug, Z, which serves as an abutment for limitingthemovement of the holderV when the latter is released by the triggermechanism before described. The corrugated orV friction surface, la.,may be of any suitable character and may be secured to the base in anysuitableV manner and its function is to insure the ignition of the matchas the head of the same is forcibly carried over said surface.Vv

To limit the setting movement of the holder I may also provide the baseplate with a stop, m, against which the heel portion of the holder willcontact, as shown in Fig. 1thus positioning the heel for its enk-Ygagement by the trigger.k The basev is also provided with a stop, n, toprevent the holder from flying backward from` left to.

right should the action of inserting ythe matchrpush the holder awayfrom the base far enough to clear the stop, Z, or in case the operatorshould pull the same clear of the said stop Z, by accident. This latterstop is set at an acute angle to the base so as to direct the torsionaleffort supplied by the spring to the holder in such a manner as willlforcey the latter against the base plate completely covering the openingand thus prevent any flame from flaring back through 'I`he4 holder isbeveled to coincide with the above angle.

The machine describedtmay be operatively held in position by variousmeans. In Fig. 2, I show the machine as being associated with aflash'sheet holder, 10, which may be SGO of any suitable type andprovided with a Hash sheet, 11, but it will be obvious that any otherform of ignitible substance as a flash powder, cartridge &c. may beemployed without departing from the spirit of my invention. Y e

The machine may be supported by any suitable means. For instance in Fig.2, I

show the machine as supported from a tableV or shelf by a suitableclamp, 12, having a seat or socket for arod, 13, which is Vfitted into asuitable opening formedV in the base plate, which may be enlarged orthickened for the purpose or provided with a socket, a', as shown inFig. 5, which socket may also serve as the means for the attachment ofla` handle, 14, if it is desired to hold the machine in the hand duringthe ignition of thel change.v s, t l

VIf itis desired to operate the machine fromyso'me remote point asuitable cord, 16, or other flexible connection may be attached to ythe'trigger and thence carried through an appropriate guidefso that when apull is exerted upon the cordthe trigger. is depressed against Vthetension of its. spring,V f, to release the heel end of the 'match holderand allow the spring, c, to turn the holder about its axis and ignitethematch by c'arrying the same forcibly over and intocontact with thecorrugated surface, It, before mentioned. Y

In operation, a match is inserted in the holder so' thatthe head only ofthe match protrudes through the hole, Z0, in the base. The holder maynow be pulled outwardly away from the Vface of the base by grasping theVmatch and turning the holder, say, to the left until the heel, b3, ofsaid holder comes into engagement with the stop, m, as shown in Fig. 1,in which position the heel of theholder will be engaged by the trigger.To ignite the match the trigger is depressed, either by the fingerengaging the head, 9,401 by pulling upon the spring or other flexibleconnection, when the spring, c, reacts to turn the holder about its axisand thereby carry the match head across in frictional engagement withthecorrugated surface, lutherie by igniting the match head and carryingthe flaming head into register with the opening, 7c, to permit the flameto pass through this opening and ignite the flash 4sheet or chargeatfthe other side of the base, said holder be-l ing rlimited in thismovement by the stop or abutment', Z, as before described. Y

rrIhe device described is intended'primarily to provide facilities forthe safe, reliable and more extended use of flash light combustibleusedchiefly in photography. lThe method of ignition described eliminatesthe possibility of an accident by the premature ignition of the flashlight combustible; it

Having thus described my invention what I claim as new and desire ytosecure by Letters Patent is f 1.
